On every page load, WordPress executes these functions in their respective order: init(); parse_request($query_args); send_headers(); query_posts(); handle_404(); register_globals(); where the main query is finished after query_posts(). Note that in this point in time, WordPress knows the template AND all the query variables like max_num_pages. In handle_404(), if the main query has any posts, the function … Read more
So far good, add taxonomy condition by checking the suburbs and states Value. // Suburbs if( !empty( $_GET[‘suburbs’] ) ) { $suburbs = $_GET[‘suburbs’]; } // States if( !empty( $_GET[‘states’] ) ) { $states = $_GET[‘states’]; } // Query arguments. $args = array( ‘post_type’ => ‘properties’, ‘posts_per_page’ => 10, ); $taxquery = array(); // if … Read more
If we have the query arguments like this $args = array( ‘queryid’ => ‘blackjack’, … ); $q = new WP_Query( $args ); Note we added one custom query argument that is not officially present in here. Now we can identify the exact query by that queryid if we use the second parameter of the posts_where … Read more
Following Milo‘s answer, I found another workaround that works and i’m more confortable with it. $args = array( ‘post_type’ => ‘post’, ‘post_status’ => ‘publish’, ‘category__in’ => array(15, 17), ‘posts_per_page’ => 4 ); $query = new WP_Query(); $items = $query->query($args);
It looks like the post titles have the date format DD.MM.YYYY. We can order the DD.MM.YYYY titles as YYYYMMDD with: $query = new WP_Query( [ ‘orderby’ => ‘wpse_mod_title ‘ ] ); that’s supported with this kind of plugin: /** * Plugin Name: WPSE-274981: Sort DD.MM.YYYY Post Titles as YYYYMMDD In WP_Query * Desription: Supported by … Read more
Here’s the culprit: [meta_query] => Array ( [0] => Array ( [key] => city [value] => Las Vegas [compare] => = ) ) Meta queries are slow, and the only way to speed them up is to not use meta queries. The post meta table is optimised for fetching key/value pairs where the post ID … Read more
<?php // get all terms of the `bank` taxonomy $banks = get_terms( array( ‘taxonomy’ => ‘bank’, // more arguments can be used, see (1) below the code ) ); // look through banks, picking one post from each foreach ( $banks as $bank ) { $args = array( ‘post_type’ => ‘account’, // your custom post … Read more
Something like this will probably work: $results = array(); $allPosts = get_posts(‘post_type=post&numberposts=-1’); foreach ($allPosts as $aPost) { if ( substr($aPost->post_content, 0, 1) == ‘<‘ || substr($aPost->post_content, 0, 2) == ‘<a’ ) $results[] = $aPost->ID; } echo “<pre>”.print_r($results,true).”</pre>”; UPDATE: but you should revisit the MySQL approach in the links you provided. This php method is somewhat … Read more
That’s not how WP_Query works, it isn’t what the documentation says either. WP_Query is not a function. foreach needs an array, or something that can be iterated on, but you’ve given it a WP_Query object. Instead, look at the documentation or tutorials, all of them follow this basic pattern for a standard post loop: $args … Read more
The close() function was added for completeness in the database abstraction. If the database is prematurely closed in a plugin or theme (as you are using it), the next call to wpdb::query() will re-open the connection. Your Commands out of sync error is a MySQL error, not a WordPress one, and it might be coming … Read more
